The Mitchell family is renting a boat for the day. The boat rental has a flat fee of $100 plus $20 for each hour. They have to pay for a whole hour even if they are not out on the lake for a whole hour. For example, if they rent the boat for 3 and one-half hours, they have to pay for 4 hours.

If they want to spend $250 or less on the boat rental for the day, how many hours can they rent the boat? Write an inequality and solve.

A) 100 + 20x ≤ 250; They can boat for 7 hours.

B) 100 + 20x ≥ 250; They can boat for 8 hours.

C) 100 + 20x ≤ 250; They can boat for 8 hours.

D) 100 + 20x ≥ 250; They can boat for 7 hours.
